MACHINEZFOR SHAPING HEEL-STIFFENERS FOR BOOTS AND SHOES.

SPECIFICATION forming part of Letters Patent No. 240,971, dated May 3,1881.

Application filed February 28, 1881.

To all whom at may concern:

Be it known that I, LoUIs Core, of St. Hyacmthe, in the Province ofQuebec and Dominion of Canada, have invented a new and usefulImprovement in Machines for Shaping Heel- Stiffenings for Boots andSlices, of which the following is a specification. My invention relatesto that class of shaplng-machines in which astiffeningto be shaped isheld closely about a heel-shaped former or male m old, with the edge ofthe stifl'enin g which is to form the flange thereof projecting beyondthe sole or tread side ofsuch former, and which is provided with meansfor bending such projecting edge down upon the former, so as to form aflange nearly at a right angle to the body or main part of thestifl'ening.

The objects ofmy invention are to so arrange the clamping-jaws thatoperate to hold the stiffening close around the former that'they shallbe contiguous to each other when so operating; and, further, to providemeans for guiding the slide, which operates to turn the flange of thestiffening in its passage over the same, in a curved path correspondingto the curve of that surface of the former upon which the flange isturned; and,further, to provide such an arrangement of operativemechanism that the several parts thereof shall be easily accessible foradjustment and repairs. To attain these objects I use the machineillustrated in the accompanying drawings, in which- Figure 1 is a ,plan,with the arm a broken away to show the screw beneath. Fig. 2 is a planof the former and clamping-jaws enlarged, with the crimping-slideremoved; and Fig. 3, an isometrical view of the principal workin gparts.

Similar letters refer to similar parts in each of the drawings.

A, Fig. 1, represents a base-plate, to which the principal parts of themachine are attached. From its rear end project the arms a a, whichsupport journals which carry the shaft B, upon which are mounted thecam-wheels C C and I). Near the opposite end of the machine is placed aformer or male mold, E, about which the stiffening to be formed is heldby the clamping-jaws c 0 c, which form a three-part female mold. (SeeFigs. 2 and 3.) This former is a heel-shaped block of metal, fastened,with its (No model.)

sole or tread surface uppermost, to the slide 1), which is fastened in agroove in the baseplate by a screw, as plainly shown in Fig. 3.

The rear section, 0, of the female luold mentioned is fastened to asliding bar, 0, that is guided in its movement by the ways (I (l, andhas an intermittent reciprocating motion through the bar f(to which itis connected by the rightand-left screwy) and the cam-wheel D, upon oneside of which is a cam-groove, in which plays a stud, h, attached to thebarf. The side sections of the mold c c are carried by the slides t i,and have an intermittent reciprocating motion in a direction at rightangles to that of the rear section, 0. This motion is communicated fromthe caln-wheels C C through the levers 7c 70, which are pivoted at 0,the ends of which carry small rolls m m, which rest against the sides ofthe cam-wheels C C, and are held thereto by the pressure of springs n itagainst the levers, near their opposite ends, to which the slides t iare attached by the connectingbars 11 p. The cams which operate thesethree sect-ions of the female mold are so shaped and adjusted that therear section in the operation of the machine is first advanced, andafterward the side sections, so as to compress an interposed stiffeningbetween themselves and the former. All three sections then remainstationary while the crimping-slide r is advanced over the top of theformer and receded, when they simultaneously recede and becomestationary in the position shown in the drawings.

The crimping-slide r is a thin plate of metal havingits front endnotched or curved in wardly, as shown, and pivoted to a flexible steelplate, .9, which is attached to a bar, it, which is adapted to slide ina groove in the upper side of the bar 0, and receives its motion fromthe connecting-rod a, which carries a stud, v, ongaging with thecam-wheel D, as shown. The crimping-plate r is movable about the pin w,by which it is attached to the plate 8, and the said pin projectingbeyond the plate on either side carries rolls a: 00. As the plates, withthe crimping-plate r,is advanced, the rolls come in contact with theguide-blocks y 3 which are curved upon their upper surfaces to conformlongitudinally to the upper surface of the former E, and thus guide thecrimping-plate at a uniform distance from the former, such 5 justcd bythe screw g.

distance being slightly less than the thickness of the flange of theinterposed stifi'enin g. This is one peculiar feature of my invention.Another is the arrangement of the side sections, 0 c, of the mold. Theseare connected to the guide-blocks y g (which are firmly fastened to theslides i i) by a dovetailed projection and groove, so as to be movablehorizontally therein, being kept in position by the springs z e. Vhenthe rear section, 0, of the mold is advanced near to the form erin theposition shown by the dotted lines in Fig. 2, and the side sections arethen moved toward the former, the beveled rear ends of the side sectionsstrike upon the beveled corners of the rear section, and are thrownslightly forward, the springs z 2 allowing such movement. This is animportant feature of my invention, as with stifi'- enings of varyingthickness it is diflicult to have the three sections of the female mold,when rigidly attached to the several sliding bars which operate them,meet and form a perfectly-continuous surface around the sides and backof the former; but with this arrangement varying thicknesses of materialmay be used for the stiftenings, and yet the side sections, c 0, will,in the operation of the machine, strike upon the rear section, 0, and,being held thereto by the springs z 2, form a continuous surface whenclosed about the former.

The rear section, 0, may have a block of rubber placed between itselfand the sliding bar 0, to which it is attached, and the position of thesame relative to the former may be ad- The side levers, k 7.",

which operate the sect-ions c 0, may be of steel and of such dimensionsas to be elastic enough to allow for the varying thickness of materialin the stilfenings; or other obvious means may be used to allow for thesame.

I am aware thatmachines have been used having a former, a three-partmold, and a crimping-slide, and do not, broadly, claim such anarrangement; but

That I do claim is- 1. In a machine for shaping hcel-stifi'enings, incombination with the former E, the threcpart female mold 0 c c", theside sections, 0 0", of such mold being automatically adjustable towardor from the rear section, 0, and operated by the slides i 17,substantially as shown and described.

2. In combination, the former E, the three part female mold a c 0",thcslides i 'i, and the springs z 2, arranged and to operate substantiallyas set forth.

3. In combination, the male mold or former E. the three-part female moldcc 0, the slides it, connecting-bars 2 p, levers 70 7c, and camwheels 0O, substantially as herein set forth.

4. In combination with the former E and means for holding a stitt'eningfirmly about it, the cri m pin g-slide 0, rolls mm, and guide-blocks yy, arranged to operate substantially as specitied.
